STATES SEUIIONAL PIIPE COUPLDQ'G Application led April 13,

This improvement relates to sectional pipe couplings of the type shown and described in my applications for patent filed on even date herewith, Serial Nos. 183,372 and a 183,373, and my object in the present instance is to provide a sectional pipe coupling which is in part adapted to be .made by stamping and pressing operations and in part by automatic screw-machine operations, thereby facilitating and chea ening the manufacture of such couplings. us, in the present coupling 1 provide a yoke member made of sheet metal which is punch-pressed or stamped to the desired shape, and which is constructed i6 to hold a separate collar or screw-threaded element for a pipe clamping nut. Such yokes and collars may be assembled with other sec'- tions to produce, quickly and conveniently, various kmds of fluid-tight couplings. AThat 80 is to say either straight or angular pipe fittings may be vreadily produced from the present sectional structure, whereby one or more ipes may be connected to another part to or om which, a liquid or fluid is to be supplied or delivered, or whereby two or more pipes maybe connected to each other. The present structure also lends itself to the making of a sectional coupling of small size and for ipes of small diameter, such as copper and rass pipe for gasoline, oil, compressed air, and vacuum connections.

In the drawings annexed hereto, Fig. 1 is a sectional view of a pipe coupling or angle fitting embodying the present improvement, and Fig. 2 a horizontal section thereof on line 2-2 of Fig. 1. Figs. 3, 4, 5, and 6, are perspective views of the body, the coupling nut and pipe, the yoke, and the clamping collar, respectivel Fig. 7 is a sectional view, on an enlarge scale, of a modified form of bod member, and Fig. 8 is a sectional view of t is same member and the yoke coupled to three pipes. Fig. 9 is a sectional view, on a reduced scale, of another form of body member. Figs. 10 to 15 inclusive, on Sheet 2, are perspectlve views of the various elements of a modification of the invention; Fig. 10 representing the body member; Figs. 11 and 13, the separate nuts and pipes which are adapted C3 to be clamped against the opposite sides of ,pipes, and a set of nuts.

said body member; Fig. 12 the `ke member; `and Figs. 14 and 15 the collars which are mounted within the yoke member for receiving and holding the nuts. Fig. 16 is a sectional view of a simple form of body member, and Fig. 17 a similar View of this member secured within a yoke member together with a pair of clamping collars a pair of flanged Fig. 18 is a sectional view of a body member having intersecting 6o passages and four sealing cones formed therein, and 19 is a sectional view of the same body member secured within a yoke member and connected to four fanged pipes. Fig. 20 is a sectional view of a body member 66 secured within a yoke member composed of two pieces each of which corresponds in shape to the yoke member shown in Fig. 5.

The present improvement comprises a body member A a yoke B for member A made of strap or sheet metal, a tubular nut C for clamplng a ianged pipe P against member A, and a screw-threaded collar D mounted within yoke B to receive nut C whereby the anged end of pipe P may be clamped against body A and said body and yoke locked rigidly together. A simple aggroupment of such parts is exemplified in Figs. 1 and 2 of the drawings, body A being formed to provide an angle litting or coupling for pipe P. Thus, body A is provided with a screw-threaded extension 2 to permit attachment to a receiving or distributing vessel or other appliance requiring a pipe coniiection, and a passage 3 extends through extension 2 to a cross port or lateral 85 passage 4 in one side of the body. Lateral passage 4 extends through the center of a shallow truncated cone 5 which is formed Within the side of the body, and body 2 may be made by screw-machine operations, using square or other angular-shaped rods cut to predetermined lengths. On the other hand yoke B may be blanked from sheet metal by punch press operations, and formed with registerin openings 6 6 in two flat sides 7-7 95 thereo to receive flat-sided body A. Yoke B may also be pressed into U-shape as shown in Fig. 5, and the flat connectingportion orside8 thereof may be formed with a round opening 9 adapted to be placed axially opposite cone 5 10 sleeved to ether. Collar D has a round boss 10 adapte to fit within opening 9 in the oke and the fianged or enlarged portion 11 o the collar is adapted to bear against the inner. ilat face of the connecting portion 8 of the yoke B. The ed e of the-flanged or enlarged portion 10of co ar D may be straight or iat to bear ainst the inner fiat surfaces of the parallel sides or branches 7-7 when said collar 'is inserted into opening 9, thereby locking the collar against turning when tubular nut C is screwed into the collar. Pipe P extends through the nut and is formed with a HaringV end fiange 12 which is adapted to lit over cone 5 when ressed against it by the tip end of the nut, and) which t1p end may be formed with a flaring mouth to seat Haring iiange 12 of the pipe. A tightly sealed joint is obtained by clampin this pipe flange against cone 5 by means o nut C, and the yoke is locked tightly upon bod A at opposite ends thereof where the straight edges 14--14 of openings 6-6 engage one fiat si e of the body. The collar and nut may be produced by automatic screw machine operations as the sectional construction of the couplin or fitting permits quantity production of iese parts with accuracy and economy in that way, including body member Moreover, the body member may be made in various forms and still permit assembly and use with other parts as described. In other words by substituting other forms of body members different types of couplings or fittings ma be produced with the same yoke, nut and co lar.

As an exempliiication, see Figs. 7 and 8, wherein a body member A is shown as having both ends 15-15 thereof open to a longitudinal assage 3 and to a lateral bore 4', and whic open ends are screw-threaded internally to receive tubular nuts C-C whereby two flanged pipes P- may be clamped against conical seats 16-16 internally of said bod member. By inserting body member A wit in a yoke B and using a collar D and atubular nut C, a T fitting is obtained for a flanged pipe P, said body also having a coni.- cal seat 5 at its side surrounding the mouth of lateral bore 4. In Fig. 9 I show a body member A which is substantially the same as body A except that its opposite ends 17-17 are screw-threaded externally instead of internally to permit attachment of body A2 to a receptacle or to screw-threaded pipes.

Other modied forms of couplings or fittings for two or more ipes are shown in Figs. 10 to 19, inclusive heet 2. These fittings comprise a four-si ed yoke member B havin rectangular openings 6-6 in two of its si es, and round openings 7-7 in its remaining sides. Thus, a body member AB such as shown in Fig. 10 may be inserted within openings 6-6 or other body members A* and A such as delineated in Figs. 16 and 18 -5 to permit four flanged Lacan?? maybe introduced into this yoke member instead to permit two anged pipes Pz-P to be coupled together by utilizing two tubular nuts C-C within a pair of screw-threaded collars D-D fitted within the round ope 7'- in the o posite ends or sides of yo member B. all these figures, the same yoke member and two collars and two nuts are m loyed to clamp abody member the alge and to couple two pipes against two cones on opposite sides of the body. In Fig.

19, body member A is formedv with four cones piepes to be coupled thereto, this body mem r corresponding otherwise to body A shown in Fig.

In Fig. 20 I show body member A4 sleeved within a pair of U-shaped yoke members B placed in overlapping relation and facing o posite directions to permit two screwtlgreaded collars D to be placed opposite the double cones for attachment of two iianged pi es by tubular nuts as illustrated in Fig. 17.
